The main character confesses to her rival that she is in love with her. The rival rejects the confession, but the main character continues to stalk the rival even going as far as wanting o become the rival's maid. There are two incestuous scenes; one has to do with a brother and a sister planning a revolt so they can be in love; the other is when the rival's sister transfers to the school and the rival tells the main character that she would rather be with her sister than her: the rival plays in into that just so that the main character can start actually doing something to earn her rival's love and affection. The rival and her distant relative refer to each other as "sister" but they are not that closely related. The first instance of incest is portrayed in a strongly negative way by the show. One character likens it to homosexuality but this is also thoroughly denounced.
